When collaborating on a large document where each person has their own section, you may want to start the page numbering at 4 instead of 1 in Word or PowerPoint.
After adding a page number in the header or footer in Word or the slide number in PowerPoint, you have the option to start the numbering with the number you want.
Word
On the Insert menu, click Page Number. Next, click Format Page Numbers.
In the Page numbering section, check Start at and enter the number you want.
In our example, the page number of the first page will be 4.
PowerPoint
On the Design menu, click the Slide Size. Next, click Custom Slide Size.
In the Number slides from section, enter the number you want.
In our example, the slide numbering will start at 4.
